Atlas Materials Testing Technology LLC (Chicago, Ill.) says its Temperature-Controlled EMMAQUA weather testing option is ideal for manufacturers of fiber-reinforced thermoset profiles for architectural windows, doors, and related building products who seek the American Architectural Manufacturers Assn. (AAMA) certification under new requirements described in AAMA 624-07, “Voluntary Specification, Performance Requirements and Test Procedures for High-Performance Organic Coatings on Fiber Reinforced Thermoset Profiles,” and AAMA 625-07, “Voluntary Specification, Performance Requirements and Test Procedures for Superior Performance Organic Coatings on Fiber Reinforced Thermoset Profiles.” The standards specify the use of concentrated, natural sunlight and require control of the black-panel temperature. Atlas offers black-panel temperature control for its EMMA and EMMAQUA testers using a patented temperature control system called Temperature-Controlled EMMAQUA. EMMA and EMMAQUA enable manufacturers to expose thermosets in outdoor accelerated weathering devices with comparable radiant dosages to materials exposed to natural outdoor conditions, but in a fraction of the time.
